UNITED STATES ARTHUR D. TEEPELL, OF LOS ANGELES, CALIFORNIA.

CONVERTIBLE PLANE.

, Application led May 5,

T all l0/10m may concern.'

Be it known that I, ARTHUR D. TnnPELL, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Convertible Planes, of which the following is a specification.

This invention relates to hand planes and consists of the novel features herein shown, described and claimed.

An object is to make a complete hand plane assembly and provide a plurality of shoes of different lengths and which may be f readily applied to the assembly one at a time to produce a working plane of the desired length.

Other objects and advantages will appear from the drawings and specification.

The drawings illustrate a plane embodying the principles of my invention.

Figure 1 is a horizontal section on the line 1--1 of Fig. 2.

Fig. 2 is a vertical longitudinal section on the line 2-2 of Fig. 1.

Fig. 3 is a vertical cross section on the line 3-3 of Fig. 2. v

Fig. 4; is a view analogous to Fig. 2 and showing the shoe only.

Fig. 5 is a view analogous to Fig. 2 and showing the plane assembly only.

The details' of construction shown inl the drawings are as follows:

The plane assembly 1 has a base 2, and sides 3 and 4, and a rear handle 5, and may otherwise bc any of the ordinary constructions. 'lhe lower face of the base 2 has rcecs-sos 6 and 7 to reduce the metal and machine work, and the extreme lower surface 8 is planed, ground or otherwise suitably finished. A downwardly and backwardly inclined face 9 is formed across the rear end of the base 2 and a similar forwardly and downwardly inclined face 10 is formed across the front end of the base 2. The handle 5 is mounted upon the base 2 and may be any ordinary construction.

The shoe 11 has an upper face 12 to Vit against the lower surface 8 and the shoe extends beyond the faces 9 and 10 and the shoes will be made in different lengths to extend more or less beyond the faces 9 and 1() as required to make planes of different lengths. A transverse lug 13 extends above the upper face 12 and is transversely 1nachilled to form a flaring slot 14 having an 1924. Serial No. 711,168.

upwardly and forwardly inclined face 15 to fit the face 9. The shoe has a finished lower face 16 for engaging the work, and has sides 17 and 18 fitting outside of the sides 3 and 1, and has a transverse opening 19 through which the blade 20 extends. A circular stud 21 extends upwardly from the shoe at the transverse center and in front of the face 10. An eccentric washer 22 is rotatably mounted upon the stud 21 and has an upwardly and outwardly flaring peripheral face 23 adapted to engage the face 10, and has an operating handle 241. The for-- ward plane handle has a sleeve portion 25 fitting upon the stud 21 against the washer 23 and has a stud bolt 26 fixed in the handle and extending downwardly and screw seated in the stud 21. The knob 27 is fixed relative to the stud bolt 26 and sleeve 25, so that by operating the knob 27 the stud belt may be loosened and the eccentric washerl 23 operated and the plane assembly 1 removed or replaced. The plane assembly 1 is bodily placed between the sides 17 and 18 upon the shoe 11 with the rear inclined face 9 engaging the lug inclined face 15, the eccentric washer 23 is rotated to tighten against the face 10, the knob 27 is manually operated to tighten the washer, and the shoe is rigidly applied to the plane assembly 1. lVhen desired, the shoe may be removed and another shoe applied.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. A plane assembly having a downwardly and baclnvardly inclined rear face and a downwardly and forwardly inclined front face, a shoe having a. lug engaging the rear face, a stud extending upwardly from the forward end of the shoe, an eccentric washer rotatably mounted upon the stud and having a beveled face to engage the front face of the plane assembly, a knob, a sleeve connected to the knob and surround ing the stud and bearing upon the washer. and a stud bolt connected to the knob and adapted to screw into the stud to hold the washer tight in its adjusted position.

2. A plane assembly having a downwardly and baekwardly inclined. rear face, a shoe having a lug engaging the rear face, an eccentric washer rotatably mounted at the front end of the shoe and having a beveled face to engage the front face of the plane assembly, and means for clamping the washer in adjusted position to hold the plane assembly.

3. A plane assembly having a downwardly und backwardiy inclined rear face and :1 downwardly and forwardly inclined front fave, :x shoe having :1 lng engaging the rear face, and means adjnstably engaging the front face to hold the shoe in place upon the plane assembly.

In testimony Whereoi:l I have signed my nume to this speoiliontion.
